Description
Technical Field
The invention relates to the field of medical instruments, in particular to an auxiliary ring cutter for a penis root prepuce operation.
Background
The redundant prepuce and phimosis are common penis deformities in clinic, urination is affected due to the redundant prepuce or the narrow prepuce opening, when urine passes through the narrow prepuce opening, the prepuce cavity is in a vesicular shape, and then the urine forms vortex in the cavity, so that prepuce scale is easy to form, and recurrent urogenital inflammation, such as prepuce balanitis, prepuce adhesion, urinary tract infection and the like, is caused. Repeated stimulation of the periderm scale may induce penile cancer if left untreated for a long period of time (mayu, 2008). Studies have shown that this is also one of the possible factors in inducing cervical cancer in spouses (Chenxiaoping, 2013).
Circumcision is the primary method of treating redundant prepuce and phimosis. The clinical circumcision mainly includes two major types, namely, traditional open surgery (such as dorsal incision circumcision) and instrument type circumcision (such as disposable circumcision anastomat, disposable circumcision stitching instrument, etc.). As is known, open surgery has many disadvantages, such as large trauma, many complications, uncontrollable aesthetic appearance, etc. These deficiencies have led medical workers to never stop their innovation, and especially after the 21 st century, some researchers have proposed the concept of "mechanized surgery and minimally invasive surgery" to bring new ideas for the innovation of circumcision.
Instrumented circumcision is a typical example of a minimally invasive surgical concept and mechanization theory. The traditional open surgery is changed to an instrumental type, the surgical steps are simplified, the surgery is gradually standardized and instrumented, and the dual purposes of improving the working efficiency (such as short surgery time and learning curve) and improving the surgical effect (such as high attractiveness, few complications and the like) are achieved. The instrument type circumcision is represented by a disposable circumcision anastomat (Chinese business ring), a disposable circumcision stitching instrument (wolf and brand), and the like.
In 2008, Peng et al (Peng YF, et al, 2008) scholars disclose the efficacy and safety of a disposable head foreskin anastomat (business ring) for treating overlong foreskin and phimosis for the first time internationally, and the operation utilizes the squeezing action between the inner ring and the outer ring of the prepuce ring to ensure that the distal foreskin is ischemic and necrotic and falls off, so as to achieve the purpose of cutting off excessive foreskin. The surgical operation mode not only changes the concept that the traditional operation must use a scalpel and a surgical scissors to carry out the operation, but also realizes the gradual change of the traditional open operation to an instrument mode, so that the circumcision has the advantages of minimal invasion, rapidness, less complication, high aesthetic degree and the like. The acao D (Cao D, et al, 2015), shidianlong (2013) and other scholars in the analysis of the meto of redundant prepuce or phimosis in the treatment of redundant prepuce or phimosis in the conventional prepuce circumcision show that the coloproctomy has unique advantages, specifically, the operation is simple, the operation time is shortened, the amount of bleeding in the operation is reduced, and meanwhile, the characteristics of few complications, light pain, high prepuce appearance fullness of patients and the like are achieved. However, in clinical application, researchers also find that the Shang-Ji has the defects that foreskin edema is easy to appear after operation, postoperative pain is more obvious (postoperative tissue necrosis and pain generated in the healing process and pain generated in ring detachment), the healing time is relatively long, and the like. Studies by the scholars of cheng jun et al (2012) showed a total incidence of complications after circumcision of the merchant ring of 8.16%, with a 4.45% higher incidence of prepuce edema. Li qiang et al (2015) found that the former not only healed long after surgery, but also pain was more pronounced upon post-operative ring removal, in contrast to dorsal open circumcision. The scholars (2013) of forest and wenbin, etc. find that the foreskin edema after the operation of the former is more serious, the pain after ring removal is more obvious, the healing time is longer, etc. in the comparison of the application of the disposable foreskin circumcision anastomat and the traditional circumcision.
Since 2012 the market of disposable prepuce head suture instruments, a great deal of research has been conducted on the efficacy and safety of disposable prepuce suture instruments for treating redundant prepuce and phimosis by a few scholars. Most scholars generally consider that the disposable prepuce suturing device for treating the redundant prepuce and phimosis has the advantages of good operation safety, light pain (no need of removing stitches and rings), few complications, high aesthetic degree and the like. However, the operation incision is not secret enough, for example, scar hyperplasia and contracture of scar constitution of a patient are inevitable, and the risk that the anastomotic nail falls off and bleeds after the operation and needs secondary suturing is possibly caused. Cao 36191, Jie et al (2013) report a disposable circumcision stitching instrument (Lang and) for treating overlong foreskin and phimosis for the first time in China, and the principle is that mechanical cutting and stitching are carried out simultaneously by utilizing the principle of a tubular gastrointestinal cutting anastomat. The research of Wangzhao et al (2014) shows that the stitching instrument type circumcision has the advantages of quick operation, short healing time, light edema degree, no pain of stitch removal and ring removal, reduction of postoperative complications, improvement of the attractiveness of incisions and the like. Bin (2017) studies found that the incidence of postoperative complications of wolf and circumcision suture was 45.6%, with higher incidence of edema, wound dehiscence, and infection, 27.8%, 8.1%, and 4.0%, respectively.
In conclusion, the traditional operation mode is adopted for circumcision, and no matter the circumcision of the foreskin sleeve skin or the circumcision of the skin at the root of the penis, the defects of complicated operation process, long operation time, long learning curve, only suitability for overlong foreskin and the like exist. The instrument type circumcision operation mode mainly adopts a disposable head circumcision anastomat and a disposable head circumcision stitching instrument. Although the method has the characteristics of simple operation, short operation time, less bleeding amount in the operation, less complications, light pain and the like, the method also has the defects and risks that foreskin edema is easy to appear after the operation, the operation incision is not secret enough, tissue necrosis is caused after the operation, the pain after the operation is more obvious (pain is generated in the healing process and the pain is generated when a ring is removed), secondary suturing is needed when the anastomosis nail falls off and bleeds after the operation. Although the circumcision on the root of the penis has more advantages compared with the circumcision on the head of the penis, the circumcision on the root of the penis is not easy to be infected by urine, the base part is larger, the lymphatic circulation is easier to establish, the healing time is shorter, the scar is small, and the like, but at present, no related instrument is used for assisting the operation in China, and the operation difficulty is larger.
